It looks like the start of the Surname 'Hugh/es' - but you have mention his surname is Edward!
I can make out that his Date of Discharge is 27/9/1919, and, he’ll receive a pension of 8/- (8 shillings) a week, commencing from the 28/9/1919.
The writing is very 'rubbed' plus it looks like the scan hasn’t covered the whole page, thus deciphering is very limiting!
